playwright 上传文件page.expect_file_chooser() 提示：playwright._impl._api_types.Error: Error: Node is not an HTMLInputElement

背景

今天有同学反馈上传playwright上传文件失败了，使用selenium也不行。

解决办法

with page.expect_file_chooser() as fc_info:
    page.get_by_text("Upload").click()
file_chooser = fc_info.value
file_chooser.set_files("myfile.pdf")

中间遇到的问题

原本想通过录制方法自动生成代码，结果在执行代码的时候提示了：playwright._impl._api_types.Error: Error: Node is not an HTMLInputElement
查看官方文档：
https://playwright.dev/python/docs/input#upload-files

with page.expect_file_chooser() as fc_info:
    page.locator("upload").click()
file_chooser = fc_info.value
file_chooser.set_files("myfile.pdf")
